MooseFS

MooseFS is the CIRC campus-wide filesystem. It is accessible from all Linux machines managed by CIRC.

Quotas

Quotas are implemented on all MooseFS directories. Hard quotas cannot be exceeded any time. Soft quotas can be exceeded for a grace period (7 days). Once a soft quota is exceeded in a directory, you must reduce your usage for that directory during the next 7 days. If you fail to reduce your usage, your soft quota starts to behave like a hard quota.

The table below shows the default quotas for common user directories.
